The Trend of Diagnosis and Treatment for In-hospital Acute ST-segment Elevation Myocardial Infarction Patients in Hebei Province From 2001 to 2011 / 中国循环杂志

ABSTRACT

Objective:To assess trend of clinical features,diagnosis,treatments and outcomes for in-hospital patients of acute ST-segment elevation myocardial infarction (STEMI) in Hebei province from 2001 to 2011.Methods:Our research was based on the information of China PEACE retrospective acute myocardial infarction (AMI) study.We conducted an analysis from 8 hospitals in Hebei province including 1 third class hospital and 7 second class hospitals for STEMI patients who were diagnosed,treated and discharged in those hospitals in 2001,2006 and 2011.The clinical features,process of diagnosis and treatment and outcomes were summarized.Results:A total of 832 medical records were enrolled.During 2001 to 2011,the mean age for in-hospital STEMI patients was increased as 63.5 years in 2001,65.0 years in 2006 and 66.0 years in 2011,P=0.0097;female ratio was similar as 30.1％ in 2001,30.7％ in 2006 and 30.3％ in 2011,P=0.9846;the ratio for cardiovascular risk factors were elevated as 69.9％ in 2001,87.1％ in 2006 and 87.0％ in 2011,P＜0.0010.In patients without documented contraindications,reperfusion rate was similar,P=0.8990 and primary percutaneous coronary intervention (PCI) conduction rate was similar.The following drug therapies were increased:aspirin (P＜0.0001),clopidogrel (P＜0.0001),β-blockers (P=0.0172),statins (P＜0.0001) and ACEI/ARB (P=0.0008).In 2001,2006 and 2011,the 7-day in-hospital mortality,the ratio of death and gave-up treatment were similar,P=0.5854 and P=0.3516 respectively.Conclusion:During 2001 to 2011,the onset age and the prevalence of cardiovascular risk factors were increased in STEMI patients in Hebei province;drug therapy for secondary prevention of coronary artery disease was elevated by years while the reperfusion rate was similar and 7-day mortality was similar.
